Topics in Algebraic Topology and its Applications I
This is a series of courses on selected important topics in algebraic topology, which aims to help the research of the graduate students and junior researchers in pure and applied algebraic topology. During this semester, our selected topics will concentrate on Leray-Serre spectral sequence and its relevant topics, consisting of Barratt-Gugenheim-Moore simplicial fibre bundles theory, simplicial approach to the Leray-Serre spectral sequence with its comparison with the classical approach in the textbooks, sampling computations of spectral sequences performed by participated students, the applications in computing homotopy groups, Witten’s twisted de Rham cohomology with its comparison with Brown’s twisted tensor products, Grigor’yan-Muranov-Yau’s delta-cohomology and Delta-twisted homology.

Lecturer Intro
Jie Wu received a Ph.D. degree in Mathematics from the University of Rochester and worked as a postdoc at Mathematical Sciences Research Institute (MSRI), University of California, Berkeley. He was a former tenured professor at the Department of Mathematics, National University of Singapore. In December 2021, he joined the Yanqi Lake Beijing Institute of Mathematical Sciences and Applications (BIMSA). His research interests are algebraic topology and applied topology. The main achievements in algebraic topology are to establish the fundamental relations between homotopy groups and the theory of braids, and the fundamental relations between loop spaces and modular representation theory of symmetric groups. In terms of applied topology, he has obtained various important results on topological approaches to data science. He has published more than 90 academic papers in top mathematics journals such as “the Journal of American Mathematical Society”, “Advances in Mathematics”, etc. In 2007, he won the "Singapore National Science Award”. In 2014, his project was funded by the “Overseas Joint Fund of National Natural Science Foundation” (Jieqing B).
